Can Agassiz's Dwarf Cichlid and Altolamprologus Compressiceps Live Together?

Agassiz's Dwarf Cichlid is a moderately assertive species (5/10), while Altolamprologus Compressiceps is moderately assertive (6/10). This modest difference means Altolamprologus Compressiceps may occasionally assert dominance over Agassiz's Dwarf Cichlid.

Agassiz's Dwarf Cichlid and Altolamprologus Compressiceps both frequent the Bottom (Substrate) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

Additional behavioural considerations to keep in mind: Two territorial species may clash over territory, especially in smaller tanks.

The safe temperature window for both species falls between 24°C and 27°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

The pH requirements of Agassiz's Dwarf Cichlid (4.5–7) and Altolamprologus Compressiceps (7.8–9) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Agassiz's Dwarf Cichlid needs 1–8 dGH while Altolamprologus Compressiceps requires 10–25 dGH.

To house Agassiz's Dwarf Cichlid and Altolamprologus Compressiceps together, plan for an aquarium of at least 150 litres with a minimum length of 90 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

Providing a mix of open swimming space and sheltered areas with rocks, driftwood, or plants will keep both species comfortable and allow natural behaviour.

Specific environmental needs for this combination include: Sand (Sifters), Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), Plants - Densely covered, Shells (Breeding/Hiding). Meeting these requirements will help both species thrive.

Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.
